A little while ago I saw a write up on how to change the bulbs on the eg hatch, but can't find it any more even with a search. My problem is that my climate control doesn't light up, but everything else does. I have checked the fuses and replaced the dimmer switch, but still no light. Next is to check the bulbs and the connection behind the clim cont. How do I remove the grey cover that surrounds the clim contr and the other switchs with out breaking it?
